GOLLAPS IBLE SHELF Filed March 6, 1929 1| uw Y r HHH H IHHHH *o O mi o Patented JulyT 29, 1930 PATENT OFFICE ROBERT eEsE, oE JERSEY CITY, NEW JERSEY COLLAPSIBLE SHELF Application filed March 6, 1929. Serial No. 344,789.

The main object of this invention is to pro vide a shelf, havinga construction of rails and lazy tongs, which lends itself to being readily and conveniently collapsed. The device is an essential accessory to delivery cars and the like in which shelves span the width of the body of the delivery car and at times are shifted out of the way. In a case of this nature, the, shelf of this application particularly lends itself to being completely collapsed and rotated to a non-obstructive position.

The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing, Figure 1 i is a top plan View of the shelf, showing the same in extended position.

Figure 2 is a view similar to Figure 1 showing the shelf in collapsed position.

Figure 3 is an end elevational view of Figure 1.

Referring in detail to the drawing, the numeral 10 indicates a sleeve which projects from a securement plate 11. A plurality of these sleeves 10 are used'in mounting a shelf in such manner that the shelf may he changed from a horizontal to a vertical position. r[he 3o shelf comprises an L-shaped rail 12 which is provided with a slot 13 extending longitudinally and lengthwise. The opposing and movable member of the shelf comprises a longitudinalstrap 14 in which short slots 15 rxr; are provided. These slots 15 are arranged in series along the entire length ofthe strap and are spaced-apartfro1n each other as shown in Figures 1 and 2. The strap 1li andthe L- shaped rail 12 are connected by a series of Ilo links 16 which extend angularly and are'in parallel relation to each other. These links 16 are connected to additional links 17 which extend in a direction at right-angles to the links 16 by pivot pins 18, as illustrated in 4.5 Figure 1. The ends of the links 16 and 17 are provided with pivot pins 19 having enlarged heads, and thesepins 19 register in the slots 15 and 13 and permit foldino of the links 16 and 17. The links 16 and 1:7 intersect each other at right-angles when the shelf is fully extended and fold into the position shown in Figure 2 when the shelf is collapsed. rlhese link members 16 and 17 are connected mutually by pivot pins 18 and are anchored to the rail 12 and the strap 14 by the pivot pins 19. 55 The rail 12 is rotatably anchored to sleeves 10 which sleeves are secured to the wall of the conveyance by means of the plate 11, any number of said sleeves 10 being used.

ln' its used position, theshelf assumes the 6o conformation shownin Figure 1 and, when completely collapsed, as shown in FigureV 2, is adapted to be rotated from the horizontal position to the vertical position and then secured in such vertical position by the hook e5 members 2O anchored to the strap 14.

lt is to be noted that certain changes in form and construction may be made without departing from the spirit'and scope of the invention. 7o I claim:

A collapsible shelf comprising a slotted rail, a slotted strap, links, all of which being movably connected to said strap and rail, said links being arranged at opposing angles to each other in the form of lazy tongs, said lazy tongs being arranged as a floor of a shelf, said links intersecting each other intermediate their length, the intersection of said links being pivotally joined, said slots being adapted se to permit displacement of the ends of said links when folding said shelf, a sleeve hingedly engaging said rail and adapted to be anchored to an upright rigid surface, said sleeve allowing` rotation of said shelf from se the horizontal to the vertical position when either in collapsed or'extended condition, a second slotted rail, hooks secured thereto for anchoring said shelf in extending and supporting position.

ln testimony whereof I afiX my signature.

ROBERT GESE.
